[The simultaneous appearance of three uncommon tumours].

A 70-year-old woman presented with nasal obstruction and pain projecting onto the left cheek. The face seemed asymmetric including exophthalmus on the right side. Nasal endoscopic inspection revealed a sarcomatous tumor located on the middle turbinate. The CT showed that the tumor filled the left maxillary sinus completely and had eroded the maxillary bone. In addition, a round, sharply defined intraorbital neoplasm on the right side was identified in the contrast-enhanced MRI. Histological examination of the extirpated intraorbital tumour showed a neurilemmoma. A tissue biopsy of the intranasal tumour falsely suggested an intestinal adenocarcinoma. Multiple neoplasms suspicious of disseminated lung metastases were detected in the CT of the thorax. One round lesion removed by thoracoscopy revealed a carcinoid. The intranasal tumour was excised completely and the histology proved beyond doubt an inverted papilloma.
